Hidden Off-Route Spots

Detour 10 km east of Écija to the Hermitage of San Pablo (5th-century Visigothic basilica). In Llerena, the Plaza de España has a unique Mudéjar-style town hall. Near Mérida, the Proserpina Dam (a Roman reservoir) is a spot for swimming. For a complete off-grid experience, hike the Sierra de Hornachuelos Natural Park, 30 km west of the A-4, where deer roam freely.

The main artery is the A-4, a well-maintained motorway with a speed limit of 120 km/h. Toll sections exist south of Córdoba (€3.50 for cars) but can be bypassed using the parallel N-IV. Fuel stations appear every 30–40 km along the A-4, with diesel typically €1.30/liter. For a budget-friendly alternative, consider the EX-103 route departing from Écija; it's slower (60 km/h limit) but cuts through charming villages and costs nothing in tolls.

• Driving time: 2h15min (A-4) / 3h (scenic)

For EV owners, fast chargers (50 kW) are available at most Repsol stations along the A-4, and at shopping centers in Écija and Llerena.

UNESCO World Heritage Sites

Córdoba's Mezquita (Mosque-Cathedral) is a UNESCO site, but the route also passes near the archaeological ensemble of Mérida, a Roman UNESCO World Heritage site.
